Several derivative and integral approximations are explored for discretizing the Nakajima–Zwanzig generalized quantum master equation (NZ-QME or GQME) to obtain discrete quantum master equation (DQME) ...

The plasmapause, as originally defined, is a steep gradient in electron density separating the region of relatively high density close to the earth, called the plasmasphere, from the region of ...

We discuss structure-preserving model order reduction for port-Hamiltonian systems based on a nonlinear approximation ansatz which is linear with respect to a part of the state variables of the ...

Abstract: In this article, we consider the identification of linear models from quantized output data. We develop a variational approximation of the likelihood function, which allows us to find ...

Abstract: The classic midpoint method for triangulation is extremely fast, but usually labelled as inaccurate. We investigate the cost function that the midpoint method tries to minimize, and the ...

Quantifying the effect of natural disasters on society is critical for recovery of public health services and infrastructure. The death toll can be difficult to assess in the aftermath of a major ...

Computing the minimal volume oriented bounding box for a given point cloud in 3D is a hard problem in computer science. Exact algorithms are known and of cubic order in the number of points in 3D. A ...

An elementary statistical mechanical model was used to calculate the folding rates for 22 proteins from their known three-dimensional structures. In this model, residues come into contact only after ...

Mitochondrial carriers are believed widely to be homodimers both in the inner membrane of the organelle and in detergents. The dimensions and molecular masses of the detergent and protein–detergent ...
